Description

Technical Field

[0001] The present invention relates to the technical field of yarn winding structures, and in particular to a yarn drum fixed winding device. Background Art

[0002] The winding mechanism winds the yarn tightly and regularly around the bobbin surface in a spiral pattern, layer by layer, to form a cylindrical, conical, or other bobbin. When the yarn is wound onto a specific point on the bobbin surface, the acute angle between the yarn's tangent and the direction of the circumferential velocity at that point on the bobbin surface is the helix angle a, commonly referred to as the winding angle. The angle between the two yarns in each direction is called the crossing angle, which is numerically equal to the sum of the two winding angles.

The fast yarn winding device described in the utility model makes it easier to assemble and disassemble the yarn drum through the drum lining, and the operation process is simpler and faster, saving the operator's operating time and improving work efficiency. The yarn roller frame and the electric telescopic rod allow the yarn to be wound back and forth onto the yarn drum, so that the yarn winding effect is better and the resistance is smaller, avoiding wear or yarn breakage.

[0004] The utility model patent with patent application publication number CN213387224U discloses an anti-wear yarn dislocation winding device, comprising a bottom plate, a first vertical plate and a second vertical plate, a guide mechanism is provided between the back of the first vertical plate and the front of the second vertical plate, an adjustment mechanism is provided between the back of the first vertical plate and the front of the second vertical plate and on the left side of the guide mechanism, the guide mechanism comprises a cross plate, the back of the first vertical plate and the front of the second vertical plate are fixedly connected to the front and back of the cross plate respectively, and the utility model relates to the field of yarn winding technology. The anti-wear yarn dislocation winding device, by providing a guide mechanism in front of the winding drum, the yarn passes through the yarn guide hole, the flannel in the yarn guide hole protects the yarn from wear, and the yarn guide block is driven to move left and right by the first electric telescopic rod, so that the winding position of the yarn can be adjusted to prevent the wear caused by the yarn winding dislocation, while the yarn can be evenly wound on the winding drum, which is more beautiful after the winding is completed.

[0005] However, it still has many shortcomings in actual use, such as:

[0006] 1. In the textile machine of the prior art, during the weaving process, the yarn bobbin rotates to release the yarn. Due to the reduced friction between the yarn bobbin and the rotating shaft, the yarn bobbin and the rotating shaft may rotate out of sync, causing the yarn bobbin to jump up and down or even fall off the rotating shaft.

[0007] 2. The up and down jumping of the yarn bobbin can easily cause the yarn to jam or even break, and the yarn bobbin will fall off the rotating shaft, which will not only affect the stable operation of subsequent textile operations, but also easily cause the yarn to become dirty and frayed, and also easily reduce the service life of the yarn bobbin.

[0008] Therefore, we propose a yarn drum fixed winding device to solve the above problems. Summary of the Invention

[0009] In order to overcome the above-mentioned defects of the prior art, the present invention provides a yarn reel fixed winding device, which solves the problems raised in the above-mentioned background technology through the cooperation and synergy between the fixing component, the first adjustment component and the second adjustment component.

[0010] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a yarn reel fixed winding device, comprising a frame, the top of the frame is connected to a working platform by bolts, a rotating assembly for facilitating the installation of the yarn reel is installed at the center position of the working platform, and a plurality of wire devices for adjusting the yarn tension are distributed in a circular array at a position outside the rotating assembly above the working platform, and a control panel is installed on one side of the working platform.

[0011] In a preferred embodiment, the rotating assembly includes a rotating cylinder, a rotating platform and a control motor. The control motor is located inside the frame and is mounted on the frame by bolts. The output end of the frame is connected to the rotating platform through a connecting shaft. The rotating platform is located above the working platform, and the rotating cylinder is installed in the middle of the rotating platform.

[0012] In a preferred embodiment, the wire guide device includes a fixing component, a first adjusting component and a second adjusting component. The fixing component is fixed above the working platform by bolts, the first adjusting component is slidably connected to the fixing component, and the end of the first adjusting component is installed with a second adjusting component for facilitating the up and down adjustment of the yarn position.

[0013] In a preferred embodiment, the fixing assembly includes a T-shaped support plate, a mounting base plate and a support seat. The number of support seats is set to two and they are stacked and distributed on both sides of the mounting base plate. Both ends of the support seat are detachably fixed to the top end of the T-shaped support plate by bolts.

[0014] In a preferred embodiment, a plurality of I-shaped slide rails are arranged in a straight line along the top end of the mounting base plate, and a positioning hole is provided at the middle position of the support seat.

[0015] In a preferred embodiment, the first adjustment component includes a hydraulic cylinder, a Z-shaped movable seat and a slider, the number of the sliders is set equal to the number of the I-shaped member slide rails, the output end of the hydraulic cylinder is fixed to the support seat by a bolt, the output shaft of the hydraulic cylinder passes through the positioning hole and extends to the middle of the Z-shaped movable seat and is fixedly connected, and the Z-shaped movable seat slides relative to each other through the sliders and the I-shaped member slide rails that cooperate with each other.

[0016] In a preferred embodiment, the top of the slider is provided with an I-shaped slide groove that is compatible with the structure of the I-shaped slide rail, the output shaft of the hydraulic cylinder is fixedly connected to the connecting flange, the connecting flange is detachably fixedly connected to the Z-shaped movable seat by bolts distributed in a circular array, and a piston hole is provided at the top of the Z-shaped movable seat.

[0017] In a preferred embodiment, the second adjusting assembly includes a hydraulic cylinder, a piston rod, a guide wheel and an L-shaped support plate. The L-shaped support plate is fixed to a side wall of the bottom of the Z-shaped movable seat by bolts. An electric telescopic rod is fixed to the top of the L-shaped support plate. The output shaft of the hydraulic cylinder is connected to the piston rod. The top end of the piston rod passes through the first adjusting assembly and extends to the top of the first adjusting assembly to connect to the guide wheel.

[0018] In a preferred embodiment, a wire channel is opened at the middle of the wire wheel and gradually deepens from the outside to the inside, and a flexible piezoelectric sensor is provided in the wire channel.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The overall structure designed by the present invention is compared with the conventional textile machine method of simply sleeve-mounting the yarn bobbin during the weaving process. Since the bottom of the guide wheel is connected to the electric telescopic rod, the guide wheel can be raised and lowered in the vertical direction. Therefore, during the winding process, the yarn guided in the guide channel can be evenly distributed up and down while being wound onto the yarn bobbin through the slow vertical movement of the guide wheel, thereby achieving uniform winding of the yarn on the yarn bobbin.

[0021] 2. The present invention provides a wire guide device. Since a flexible piezoelectric sensor is provided on the wire guide wheel, it is possible to measure the force of the yarn perpendicular to the center of the wire guide wheel and deduce the tension of the yarn. Further, according to the tension of the yarn, the distance between the wire guide wheel and the rotating drum and the rotation speed of the rotating drum are adjusted. Thus, during the yarn winding process, the distance between the wire guide wheel and the rotating drum is first set to the minimum. When the yarn thickness in the yarn reel increases, the length of the piston rod at the output end of the hydraulic cylinder retracts, causing the distance to continue to expand. Therefore, during the yarn winding process, the yarn is always subjected to uniform force, which does not cause the pay-off to jam or the yarn to break.

[0022] 3. The overall structure designed by the present invention can fix the yarn bobbin on the rotating platform, avoiding the phenomenon that the yarn bobbin and the rotating shaft rotate out of sync due to the reduction of friction between the yarn bobbin and the rotating shaft, and the yarn bobbin jumps up and down or even falls off the rotating shaft.

[0036] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0037] As attached Figure 1-7 The shown device is a yarn drum fixed winding device, comprising a frame 1, the top of the frame 1 being connected to a working platform 2 by bolts, a rotating assembly 3 for facilitating the installation of a yarn drum being installed at the center of the working platform 2, three wire devices 4 for adjusting the yarn tension are distributed in a circular array above the working platform 2 and located outside the rotating assembly 3. During the winding process, the yarn is evenly wound on the yarn drum by slowly moving the wire device 4 in the vertical direction, and the pulling force on the yarn is adjusted by slowly moving the wire device 4 in the horizontal direction, and a control panel 5 is installed on one side of the working platform 2.

[0038] Please refer to Figure 2-3 , the rotating assembly 3 in this embodiment is described in detail. The rotating assembly 3 includes a rotating drum 31, a rotating platform 32 and a control motor 33. The control motor 33 is located inside the frame 1 and is installed on the frame 1 by bolts. The output end of the frame 1 is connected to the rotating platform 32. The rotating platform 32 is located above the working platform 2. The rotating drum 31 is installed in the middle of the rotating platform 32. The control motor 33 is started by the control panel 5. The output end of the control motor 33 is connected to the connecting shaft through a coupling and a reducer. The other end of the connecting shaft passes through the top of the frame 1 and the working platform 2 and extends to the top of the working platform 2 and is connected to the bottom center of 32, thereby driving the rotating platform 32 to rotate. When the rotating platform 32 rotates, it drives the rotating drum 31 to rotate, and the yarn reel is sleeved in the rotating drum 31 to ensure that the yarn reel is always stably fixed on the rotating platform 32 during winding. It is worth mentioning that the yarn first extends from the outside of the working platform 2 to the top of the working platform 2, and passes through the three wire devices 4 in sequence, and is finally wound into the yarn reel sleeved outside the rotating drum 31.

[0039] Please refer to Figure 4The thread guide 4 in this embodiment will be described in detail. It includes a fixing assembly 41, a first adjustment assembly 42, and a second adjustment assembly 43. The fixing assembly 41 is fixed to the work platform 2 via bolts. The first adjustment assembly 42 is slidably connected to the fixing assembly 41. A second adjustment assembly 43 is mounted at the end of the first adjustment assembly 42 to facilitate vertical adjustment of the yarn position. Because the fixing assembly 41 and the work platform 2 are fixedly connected, when the first adjustment assembly 42 is activated, the fixing assembly 41 remains stationary, allowing part of the first adjustment assembly 42 to move forward. The coordination between the fixing assembly 41 and the first adjustment assembly 42 is described in detail below. A sensor mounted on the second adjustment assembly 43 measures and calculates the yarn tension. Based on the yarn tension, the rotation speed of the rotating assembly 3 and the distance that the first adjustment assembly 42 pushes the second adjustment assembly 43 to slide—that is, the distance between the second adjustment assembly 43 and the rotating drum 31—are adjusted. The second adjustment assembly 43 is used to vertically raise and lower the thread guide. During the winding process, the slow vertical movement of the thread guide ensures uniform winding of the yarn around the bobbin.

[0040] Please refer to Figure 5 , the fixing assembly 41 in this embodiment is described in detail. The fixing assembly 41 includes a T-shaped support plate 411, a mounting base plate 412 and a support seat 414. The number of support seats 414 is set to two and they are stacked and distributed on both sides of the mounting base plate 412. Both ends of the support seat 414 are detachably fixedly connected to the top of the T-shaped support plate 411 by bolts. In this way, the overall structure is fixed above the working platform 2 as the initial spacing between the second adjustment assembly 43 and the rotating cylinder 31.

[0041] Please refer to Figure 5 , further illustrating the fixing assembly 41 in this embodiment, a plurality of I-shaped slide rails 413 are arranged in a straight line along the top of the mounting base plate 412, and a positioning hole 415 is opened in the middle position of the support seat 414 to facilitate 42 to move along the I-shaped slide rails 413 above the mounting base plate 412, thereby adjusting the distance between the second adjustment assembly 43 and the rotating cylinder 31.

[0042] Please refer to Figure 6, the first adjustment component 42 of this embodiment is described in detail. The first adjustment component 42 includes a hydraulic cylinder 421, a Z-shaped movable seat 422 and a slider 423. The number of sliders 423 is equal to the number of the I-shaped slide rails 413. The output end of the hydraulic cylinder 421 is fixed to the support seat 414 by a bolt. The output shaft of the hydraulic cylinder 421 passes through the positioning hole 415 and extends to the middle of the Z-shaped movable seat 422 and is fixedly connected. The Z-shaped movable seat 422 slides relative to the I-shaped slide rail 413 through the mutually cooperating slider 423. The top of the slider 423 is provided with an I-shaped slide groove 422 that is adapted to the structure of the I-shaped slide rail 413. 4. The output shaft of the hydraulic cylinder 421 is fixedly connected to the connecting flange 425, and the connecting flange 425 is detachably fixedly connected to the Z-shaped movable seat 422 by bolts distributed in a circumferential array. A piston hole 426 is provided at the top of the Z-shaped movable seat 422. Since the hydraulic cylinder 421 is fixedly connected to the support seat 414 by bolts, when the hydraulic cylinder 421 is started, the position of the hydraulic cylinder 421 itself on the working platform 2 remains unchanged. As the piston rod of the hydraulic cylinder 421 extends, the hydraulic cylinder 421 pushes the Z-shaped movable seat 422 to move slowly above the mounting base 412, thereby changing the distance between the second adjustment component 43 and the rotating cylinder 31.

[0043] Please refer to Figure 7 The second adjustment component 43 of this embodiment is described in detail. The second adjustment component 43 includes a hydraulic cylinder 421, a piston rod 432, a wire pulley 433 and an L-shaped support plate 435. The L-shaped support plate 435 is fixed to the bottom side wall of the Z-shaped movable seat 422 by bolts. The top of the L-shaped support plate 435 is fixed with an electric telescopic rod 431. The output shaft of the hydraulic cylinder 421 is connected to the piston rod 432. The top end of the piston rod 432 passes through the first adjustment component 42 and extends to the top of the first adjustment component 42 to connect to the wire pulley 433. A wire channel 434 is opened in the middle of the wire pulley 433, which gradually deepens from the outside to the inside. A flexible piezoelectric sensor is provided in the wire channel 434.

[0044] The electric telescopic rod 431 at the bottom is started through the control panel 5. The piston rod of the electric telescopic rod 431 extends to push the piston rod 432 to move up and down, further driving the wire pulley 433 to move up and down. During the winding process, the yarn is evenly wound on the yarn bobbin by slowly moving the wire pulley in the vertical direction. In addition, the flexible piezoelectric sensor provided on the wire pulley 433 can measure the force of the yarn perpendicular to the center of the wire pulley 433, and calculate the tension of the yarn, so that the distance between the second adjustment component 43 and the rotating drum 31 and the speed of the rotating drum 31 can be adjusted according to the tension of the yarn.

[0045] The control motor 33, hydraulic cylinder 421 and electric telescopic rod 431 involved in this embodiment can all use conventional parts in the prior art, and their supporting hydraulic systems, solenoid valves and pipelines can also be provided by the manufacturer. In addition, the circuits, electronic components and modules involved in the present invention are all existing technologies and can be fully implemented by those skilled in the art.
